4.1.3 Digital Output

4.1.4 RS-232

R3000 supports digital output with wet

contact. Please refer to the right side figure

to connect the negative pole of the power

to the port marked “GND”.

The maximum output voltage, output

current and output power of DO is 30V DC,

0.3 A and 0.3 W respectively. It means that

the voltage difference between Out1, Out2

and GND cannot exceed to 30V DC; and the

current value through Out1 and Out2

cannot exceed to 300 mA; while the output

power dissipated by Out1 and Out2 cannot

exceed to 0.3W. Otherwise, the DO will be

damaged.

R3000 supports one RS-232 for serial data

communication. Please refer to the

connection diagram at the right side.
